u' Toizll it cimcern Be it known that I, ASA F. HUCK, "t titi! zen of the United. States, residing atEaston in the county of Northampton-and. State o Pennsylvania, have invented ynew ,and useful Improvements in Stovepipe-Anchors, of which the following isa specification.

` 'lhisinvention relates to stove'pipe 'anchers, 'and particularly to 'means for securing a thimble and, pipe within a flueopent ing, whereby casual dis'lacement of the.v

stove pipev and thimble will be prevented.

The primary object ofthe inventionis to provide a. clamping device which, uponthe application of thepipe and thimble, `may be adjusted from an external point to bring a clamping device upon the thimble'into engagement with the pipe and wall of the flue-opening, whereby the pipe and thimble lwill be held rmly against relative movement or displacement.

A further object of the invention'is to provide a simple, reliable and eflicientcon struction of clamping device and adjusting means which may be readily and conveniently appliedjto the thimble for use.

The invention consists ofthe features of construction, combination and arrangement` of parts hereinfully described and claimed, reference being had to the accompanying drawing in which Figure 1 is a horizontal section through a stove pipe, thimble and flue wall, showing the application of the invention. lFig. 2 is a fragmentary elevational view looking toward the clamp from the interior of the thimble. Fig. 3 is a side ,elevation showing the clamp in position to ermit insertion or withdrawal of the thim le. Figs. 4 and 5 are detail views of the clamp and coupling plates, res ectively. Fig. 6 is a view in side elevation o the thimble ange removed from the pipe. t

Referring to the drawing, 1 designates a flue or chimney provided with the usual flue opening Vor passage 2, within which is located the end of a stove pipe 3 encompassed by a thimble 4 provided with a iange or joint closing ring 5.

The thimble is provided With a T-shaped slot 6 to receive a clamping member or cross piece 7 upon one end of a clamping plate 8, said member or head 7 being adapted for engagement with the thimble 4 when the clamping plate is in a predetermined position.

Speoication of LettersjPatent. i Patete imputation medjoctober a, 1914. "serialnofseas'eof scription that the T-shaped coupling. u clamping-headformed by the parts '9 maybe engagedf'with-the thimble by first tending through 'the cross portion-of the slot 6 'and coperating with the' member l7 tov produce ka T-shaped coupling and clamping member adapted to be moved into'and` out'of clamping engagement .with thestove pipe.'

- The plate 8 isof rectangular or oblong rectangular' form-'and atY its end opposite the head 7 is 4provided withspurs or biting d Mar. 16, 1915.

-rht member .offhe'tti 7- is oasi-t fram the plane ofthe. A'plateSand connected there- 'tol projections 10 bent inwardly at the opposite sides thereof and adapted for engagement `with the .wall of the flue opening. 2 to hold v theuclamping plate against y,oustvvard movement.`

Y. It will evident th'e'foregoing-deand and disposing said head longitudinally of the thimble and passing it'through the. longiafter whichlby imparting a quarter .revolu tionto the clamping plateand disposing the tudinally of the thimble land at the same timewill be locked against relative displacement. The construction is also such that the ofi-setting of the portion 7 in the manner described adapts the same by reverse swinging movements of the clamping plate to be moved into and out of clamping position with relation to thepipe 3, as will be readily understood. V v

The clamping plate 8 is formed with an elongated slot 11 to receive a T-shaped coupling head 12 upon the rear end of a coupling plate or member 13, the opposite end of which is formed vwith an inwardly bent right angular flange 14 provided with a screw threaded opening 15. This opening lre'ceives an adjusting screw 16, having a headed end 17 projecting outwardly through an opening 18 in the flange 5. If desired, a bearing plate 19' may be secured to the thimble and formed also with an opening for the passage of the screw, by which tudinally extending portion of the Slot 6,

greater 'strength and durability will be protween the thimble and a portion of the wall if 2 l of the opening 2, and the head 17 of the member 8 is adapted to engage a locking depression or recess 7 in the pipe 3.

In disposing the parts of the clamping device for the application oi the thimble, the adjusting screw is so arranged relatively to the coupling member as'to dispose the coupling member and clamping plate in a position substantially parallel with the wall of the thimble, as .shown in Fig. 3, thus holding the offset engaging ends of the clamping plate in retracted position and Y permitting of the application of the thimble.

lVhen the-thimble is applied the screw may be adjusted to draw the coupling plate out ward whereby the clamping plate will be swung outwardly and-forwardly at an angle to the thimble, as shown in Fig. 1, so that its head 7 will engage the depression 7 in the pipe 3 and its spurs 10 the wall of the opening 2, thus binding and locking the thimble againsty either inward or outward movement and also binding and locking the pipe 3 against movement in any direction, whereby casual displacement of the parts will be obviated. It will be observed that this result is secured by means of a simple construction of clamping device which may be easily and conveniently applied, ineX- pensively manufactured, and which in operation will eiiiciently serve to perform its intended function.

1. In a stove pipe anchor, the co'mbination of a stove pipe, a thimble body, having a flange atone end thereof, a clamping plate pivotally mounted upon the body for swinging movements and having clamping portions to respectively engage the stove pipe and the wall of a flue opening, and means for externally adjusting said clamping device to swing the same to clamping and nonclamping position.

2. ln a stove pipe anchor, the combination of a stove pipe, a thimble comprising a body having a flange at one end thereof, a clamping member pivotally mounted upon the thimble body for movement into and out of clamping engagement with the wall of a flue opening and the stove pipe, a coupling member connected with said clamping meml ber,. and an adjusting device extending through the ange of the thimble and connected with said coupling member.

3. In a stove pipe anchor, the combination of a stove-pipe, a thimble having a T-slot and a flange, a clamping plate having an offset T-shaped clamping member at one end pivotally engaging said thimble, said member being adapted for engagement with the stove pipe and the opposite end of said clamping plate being provided with spurs for engagement with the wall of a flue opening, a coupling member detachably connected with the clamping plate, and an adjusting screw engaging said coupling member and extending outward through the flange, whereby said' clamping plate may be adjusted. r
